Running shoes in the office?

American’s are the worst dressed people in the world, and their worst custom is the wearing of tennis shoes or running shoes with everything and anything. I’ve even seen tennis shoes worn with a tuxedo! Tennis shoes are for playing tennis, exercise or jogging. With jeans you should wear work shoes if you’re working, and if you are going to the market in jeans, wear a pair of loafers. Tennis shoes are NOT OK for the office or for any job, unless you are an athletics or fitness coach. I wish Americans would wear shoes that are appropriate to what they are doing.
